Subject: [PATCH] [ARM] Armv8-R does not require fp64 or neon.
Specifying cortex-r52 still enables neon and fp64.
Change the default Armv8-R cpu from cortex-r52 to generic so it will not
enable these features by default.
Remove the GENERIC case from llvm/test/CodeGen/ARM/useaa.ll because it
is the same as the USEAA case now that AA is enabled for all targets.

Changes to the ARM Backend
--------------------------

* FEAT_F32MM is no longer activated by default when using `+sve` on v8.6-A or greater. The feature is still available and can be used by adding `+f32mm` to the command line options.
+* armv8-r now implies only fp-armv8d16sp, rather than neon and full fp-armv8. These features are still included by default for cortex-r52. The default cpu for armv8-r is now "generic", for compatibility with variants that do not include neon, fp64, and d32.
